Charlotte NC Investing- First Time- Am I late to the party?

[Charles Eng]

I'm new to real estate investing and I narrowed down my choices down to Charlotte NC and Gastonia NC. Every time I make an offer on a property, it's bought up in a day and usually in cash. I find that NC properties cash flows decently ($200 to $400), huge tenant demand, and much room for appreciation. I was suggested by my real estate agent to have preapproval letter ready at hand so I can get ahead of the pack. Do you guys have any suggestions to how I can obtain a property in Charlotte? Like through a wholesaler?
